Tutorial: Open ports on the router

Let's be honest, the tutorial is not mine, it belongs to the user Enter (k) of the forum elhacker.net. Thank you for this good tutorial and I hope that it'll help you. Remember that each router is different and therefore, the images don't have to necessarily coincide with those of the tutorial. If any doubt, don't hesitate to comment.

Tutorial

The first thing we need to know is the gateway of our LAN network, namely our Private IP router, this is called IP Gateway. To know that, we open a console IP, (if we are in Linux a normal terminal, and if we are in Windows a command prompt ) then we run the command:

Code:

 ipconfig

If we are in a Windows system, and if we are in a Linux, the command:

Code:

 ifconfig 

Both commands printed something like:



We know already the IP gateway, namely to access our IP router and its configuration. We can access (usually) in three different ways:

• Through configuration ISP CD, if you have not read this CD manual, since everything becomes easier, although a bit slower.
• Through the browser (Internet Explorer, Firefox, Netscape, etc.) put the IP address of the gateway and passing the login (now we will see how to pass this login if we do not know nor our own user name and password)
• Through telnet, making telnet. This method is perhaps the fastest, but it is the least that people like.

I'm going to show you how to access the settings through the browser.

1]Open the browser and write the IP gateway, in my case is 192.168.1.1, therefore address is:

http://192.168 .1.1

But this varies depending on each machine, etc. router.

Now we'll be asked for a log-in, that will pass without problem since the username and password will be by default. To know this username and password by default, we must know the model of the router and do a google search. I already know a very useful page:

So far standard routers. There are routers that I did not post for the simple reason that they have no Login, so why put them? I have a Zyxel Prestige 660H, so my user is 1234 and my password 1234:



Okay, we move from the Login, router varies in each form. I will explain the basic form, but in each router is different. You can consult www.adslayuda.com to get the complete manual on this.

The basic way:

• Access the router via the Login
• Search a Setup menu or Advanced Configuration
• We seek a ports menu setup , NAT, SUA or something (I say "something like" because as I said in every router is different, but basically this is it)
• This menu will leave something like the following picture:

Start Port No. Here we will put the port number through which we started to open some routers sometimes give us the option of what kind of open port we want (either TCP or UDP), then open TCP and UDP.

End port No. The port number till we want to open.

For example, if we want to open port 3335 TCP
Start Port No. 3335 End Port No 3335 and is already our ip :D.

IP Address Here we put our private IP, that we can know through

We apply changes, reset the router and it will open ports, since it serves to make the ID eMule high, for example, or if we have any control program Remote power used properly.


I hope that all well explained. Any questions or comments please post them.
